The United Fresh Fruit and Vegetable Association, not exactly known for big marketing efforts, will soon begin a return-to-spinach blitz, reports Ad Age. Details and timing seem undetermined - lots will depend on when the FDA gives the all-clear. The basic pitch, of course, will be that spinach is not only safe but good for you. Also looking at an ad campaign is Earthbound Farms, which has been at the center of the investigation. There are signs that spinach grown in states other than California might be back on the market sometime soon. Investigators are now focused on Monterey, San Benito and Santa Clara counties.
